Hello, I am having difficulties completing the problem, mainly part three. I can get all the account titles correct, just not the right numbers. Any help would be great!

Blanton Plastics, a household plastic product manufacturer, borrowed $9 million cash on October 1, 2027, to provide working capital for year-end production. Blanton issued a four-month, 15% promissory note to L&T Bank under a prearranged short-term line of credit. Interest on the note was payable at maturity. Each firm’s fiscal period is the calendar year.

Required:

  1. Prepare the journal entries to record
    1. (a) the issuance of the note by Blanton Plastics and
    2. (b) L&T Bank’s receivable on October 1, 2027.
  2. Prepare the journal entries by both firms to record all subsequent events related to the note through January 31, 2028.
  3. Suppose the face amount of the note was adjusted to include interest (a noninterest-bearing note) and 15% is the bank’s stated discount rate.
    1. (a) Prepare the journal entries to record the issuance of the noninterest-bearing note by Blanton Plastics on October 1, 2027, the adjusting entry at December 31, and payment of the note at maturity.
    2. (b) What would be the effective interest rate?

Additional Mathematics—Pending OP Reply [College Math] Significant figures question

1 Upvotes

This assignment is for my college biology class but I’m still going to categorize it as math.

I don’t have much, if any experience working with significant figures. I may have learned about it during one of my intro to biology classes in high school, but I’m not sure.

Originally, I thought the length of the tibia bone would have been 34.4, but every answer I have submitted ranging from 33-35 has been incorrect. There is hardly any information regarding significant figures in the instruction and information section of the assignment.

Any help would be appreciated.

Solved: Answer was 34.41

High School Math Confusion of integration by parts [Calculus BC]

1 Upvotes

I am confused on this derivation of integration by parts, or what integration by parts really means to be the inverse of the product rule. Why in the integral it's just f(x)g'(x), as the general form of the antiderivative that can be solved by integration by parts, when the product of two functions' derivate is f'(x)g(x) + f(x)g'(x). Shouldn't the inverse of that take the antiderivative of '(x)g(x) + f(x)g'(x) and yield f(x) g(x)?

Further Mathematics [University level Abstract Algebra: Symmetric groups] Can anyone explain to me the symmetric groups and especially the subgroup problem described below?

1 Upvotes

I have this task and I don't know how to solve it despite having all the basic knowledge required for it. I can't 'connect the dots' so to speak.

a) Find the max element order in S_{10} - symmetric group consisting of 10 'base' elements and its order being 10!

b) Let s be some element of max order from S_{10}, find sgn(s) as well as s^{2040}.

c) If H is a subgroup of S_{10} and H contains an element of max order, then H contains the equal number of even and odd permutations. Prove it.

I've never encountered a task like this so I genuinely don't know how to think it through.

a) My intuition says I should find the lcm of prime cofactors of 10, so lcm(2, 5) = 10. I genuinely don't know how to do it. This also doesn't add up in my logic because 2+5 = 7. So maybe lcm(2, 3, 5) = 30? But I arrive to that answer by pure luck and need some explanation why is that.

b) Would depend on a) but let's say it is 30. What is sgn(s)? I've never seen it before. I do recall it might be odd vs even number of elements in a single disjoint cycle, odd ones starting with a minus. But how would I take that order of 30 and split it into smaller, disjoint cycles? so I would have sgn(s2) sgn(s3) sgn(s5) where s2, s3 and s5 only represent the disjoint cycles of 2, 3 and 5 elements. So in front of sgn(s2) there will be a + and in front of 2 others - so it would be positive in the end?

s^{2040} I did similar stuff before, I can do 30 = 0 mod(2040) (because 30*70 = 2100, 2100-(2*30) = 2040) so therefore s^{2040} = s^0 so nothing changes (and even if it did, I have no given s explicityl so I have no idea what am I supposed to do, s^{2040} only shifts all the elements in each disjoint cycle, but here s isn't given so there are no specific disjoint cycles i have to shift, confusing)

c) Most challenging part and the one I don't understand at all. Need full help and ELI5 explanation for this one haha

If you did read everything, thanks a lot!!!

Stuck on this last problem, hoping someone can give me some advice how to tackle it. I thought it looked like a good equation for exactness but that didn’t work. I asked chat gpt and it said something about shifting the variables so y=y+1 and x=x-1 or something like that but that doesn’t look like anything we’ve covered in class yet. We have done homogeneous equations where I have to substitute in u=y/x and stuff like that but I’m struggling to see how that would help here.

Literature—Pending OP Reply [College English: Personal narrative] How should I approach a personal narrative differently from a fictional narrative or research paper?

3 Upvotes

Hello ppls. I have a writing project right now and we are writing about community. The first step of the project is to write a personal narrative about an experience within one of your communities. This narrative will later be used to write an essay on whether or not our ideas of community are worth exploring.

I wanted to write about my experience in high school marching band. Specifically my first competition. I want to later use this as evidence for why expression and creation is what makes communities.

Right now this first part of just writing about the experience has me stumped. It’s been a few years since I was last in school and even longer since I wrote an actual personal narrative. The last few years of high school we were really on writing research papers or just taking tests. I never really got to write a narrative.

I also want to try to keep it very grounded. I want to make the reader feel like they are in my shoes and can feel what I felt but I don’t know how to explain this without doing too much where it almost feels fake.

Any advice is appreciated!

My math teacher mentioned something about using a graphic calculator (CX II-T) to solve specific questions but I just got really lost midway and I have no idea how to start, what steps to take, or what formula or equations to use 🥹

So far, I've gotten that the equation of the line (4,2) and (7, -2) is 4x + 3y - 22 = 0 [fact check or correct way to solve would be appreciated!]

After that im completely lost, MAB = MBC then solving them simultaneously but then the teacher did something on the calculator (IDK WHAT HE DID) and got c = 1? Does anyone know how 😭

And for questions A, B, and C, those are the ones im completely lost in 😔

Further Mathematics—Pending OP Reply [College: Math] AI reliance when solving homework

21 Upvotes

Recently (over the past year), I feel like I've been overly reliant on AI for homework. I gaslit myself into thinking I was using it "responsibly" (using learning mode, telling it only to give vague hints, etc.), but I feel like that had a negative effect on my problem-solving skills. Because of this, I decided to stop using AI this semester to see if it would help.

Now I feel helpless when working through problems, especially in pure math. If you're in a similar position, please stop using AI. Even though it gives vague hints, those hints are usually the difference between figuring it out yourself and not.

My motivation has gone way down since everything is much harder and I procrastinate more. What should I do when I hit a wall where I’d normally turn to AI? Does this get better with time after solving more problems, and is pushing through it actually worth it?
